I admire this guy’s inventiveness, but if I lived in Germany and was limited as to what I could build to non-firearms, then I’d experiment with things like steel balls flung by high RPM electric motors. Spin it fast, and release! It might not be any more powerful than his slingshots, but it would certainly be more compact.

And that’s still somehow safer and less lethal than the machete slingshot.

When’s he gonna make the Grenade slingshot, where firing it also pulls the pin for maximum distance? Or the Molotov slingshot with friction activated flame? Or the “Sweet mother of god why” Nuclear slingshot with the Gun type ignition?
